Details
The TK1744MD Pulley Wheel Set is a high-performance upgrade designed for SHIMANO® 12s GRX Di2. It includes both thicker (carbon) and thinner (alloy) dust caps to ensure proper fitment across various models. Thicker dust caps are intended for SHIMANO® MTB and most traditional SRAM® Eagle™ derailleurs, while thinner alloy caps are specifically for SRAM®’s latest T-Type™ Eagle Transmission models. Installation is straightforward with a 3 N·m torque specification, and fine-tuning may be required for optimal derailleur performance.
Please refer to the product manual to select the correct dust caps for your specific derailleur model. Proper chain length is also critical to drivetrain efficiency and longevity.
